I teach and conduct research to solve problems that will make the world better: safer, healthier, and happier. Working with undergraduates, graduate students, post-docs, and other faculty, we develop humanoid robots for disaster recovery, robots to inspect trees for invasive insect pests, and autonomous boats for monitoring lakes. In the past I have worked on medical imaging to improve cancer and heart disease diagnoses and treatment, and spatio-temporal databases for global change research. In my spare time I like to hike, bike, ski, canoe, and play frisbee.
